NON-REFILLABLE BOTTLE.

Application filed January 22, 1906. Serial No. 297,170.

Specification of Letters Patent.

Patented Nov. 6, 1906.

" To all whom t may concern:

duce a bottle w ich may be filled in the firstinstance from the bottom thereof and then so closed that it cannot be subsequently refilled through the same aperture.

My invention further relates to such a construction'of bottom as will permit the assage therethrou h of certain mechanica arts used in an about the neck of the bott e for permitting the flow of a liquid in one direction only.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which similar characters of reference indicate corresponding parts in the figure.

The iigure is a vertical section through a bottle provided with my invention.

The body portion 4 of the bottle is provided with a conoidal portion 5, separated therefrom by an annular constriction 5a. The conoidal portion 5 merges into a bulbous portion 6, 'above which is an annular constriction 6a. Another conoidal portion 7 of the neck is provided with inletpassages 8 and is threaded externally. Ametal ca 9, threaded internally at 10, is provided wit an annular'hood 11, integral therewith, and encircled by this annular hood is an annular cork member 12, fitted neatly over the apertures 8. By screwing the cap 9 downwardly upon the ortion 7 of the neck the annular cork 12 is orced firmly into engagement with the portion 7, so as to close the'outlet-a ertures 8. An annular cork13 is encircle by the conoidal portion 5 and is engaged internally by a sleeve 14, provided with a flange 14a and made of any desired material, preferably glass or metal. The sleeve 14 is `provided With inlet-apertures 14b and with outlet-apertures 14c for permitting the liquid contents of the bottle to be removed. A hollow valve 15 is provided with a closed end 15a, upon which 1s secured a fastening 16,

and connected with this fastening is a spiral spi'in 17. A plug 18 is supported in a bridge 19, which by the tension of the spring 17 is drawn tightly against the adjacent end of the sleeve-14, as will be understood from the drawing. When the bottle occupies the position indicated in the drawin or merely rests upon its side, the tension of the spring 17 maintains the hollow valve member 15 in contact with the annular cork 13, so that none of the liquid can escape. When, however, the bottle is inverted or turned beyond/a predetermined an le, as indicated in the drawing, the wei ht o the valve member 15 causes it to stretc the spring 17, so that the liquid is free to ass from the bodyA ortion 4 of the bottle, tIi apertures 14C and 8, thus making its escape.

`The cap 9 is of course removed from the bottle for the purpose of allowing the contents to flow out. i

In order to insert the valve member 15, the annular cork 13 the sleeve 14, and parts carried by these members, they are first assembled and are next inserted through the bottom 4a of the bottle. This bottom is provided with an annular flange 4b inte ral therewith, this flange projecting upward y and inwardly and terminating at its top in a ragged edge 20. This ragged ledge may conveniently be made by breaking away an excess of glass from the iiange 4b, the natural break or ragged edge formed by the fracture giving the flange' 4b an excellent edge or surface, as indicated in the lower portion of the drawing, the plug 21 terminating inwardly in a flange 23. An annular cork member 24 encircles the lug 21 and is disposed intermediate of the anges 22 23.

In order to insert the valve 15, annular cork 13, and sleeve 14, these parts are first assembled and are let into the bottle from the bottom thereof, the bottle being preferably inverted for this pur ose. The annular cork 13 being yielding is orced past the constriction 5a, whereupon all of the parts assume the position indicated inthe drawin and cannot readily be displaced. The liqui contents is now oured into the bottle through the bottom, an the plug 21, provided With the annular cork member 24, 1s forced into the bottom, so as to be encircled by the annular ange 4b. The annular cork 24 being once in contact with the liquid 25 kbegins to swell at its inner portion 24a, and in swelling'- it naturally obtrudes more or less over the broken surface 24, which being rough and jagged, as aboved described, cuts into the e apertures 14h, an the loo IIO

cork to a greater or less extent and effectually prevents the removal of either the annular cork 24 or the plug 21. The greater the tendency of the portion 24a of the cork to swell the more tightly is the plugdrawn into the annular aperture constituted by the annular flange 4b, as will be readily understood from the drawing. l

As will be seen from the above, the bottle cannot be readily reiilled from either of its ends.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a non-rellable bottle, the combination of the body portion, an annular flange supported thereby and provided with a broken or jagged edge, and aclosure member encircled by said annular member, and provided with a portion to be engaged by said broken or jagged edge. Y

2. In a non-reillable bottle, the combination of an annular member projecting internally and provided with a gripping edge, a member provided with a yielding surface and adapted to be forced into said annular member and grip ed thereby.

3. A non-reiil able bottle comprising a body portion provided with a bottom, said bottom having an annular flange integral therewith and projecting internally of said body portion, said annular flange having a rough jagged edge of uncertain conformity, and a closure-plug provided with a portion of l resilient material, for engaging the said edge.
